A multimodal approach for the automation of mechanical design is proposed. It is based on nonlinear programming incorporating topology optimization (TO) and multiple modes of mechanical analysis of the structure. The material plastification, large strain and transient failure behavior of interim optimized designs are evaluated in a nonlinear analysis. As a result, early stage validation of results from topology optimization (TO) and automatic design iteration are achieved.
A design approach is implemented, which is based on generative design and aims for safety and lightweight construction under the aspects of structural ductility and fail-safe behaviour in overstraining. The scheme is developed with a high degree of automation, such that effective weighting of technical design criteria can be achieved and design optimization results can be directly manufactured. The application is demonstrated in simulation analysis as well as through experimental testing of 3D printed structures.
